Estrogen deprivation and vaginal function in postmenopausal women

Area of Science:

• Gynecology
• Reproductive Endocrinology
• Physiology

Background:

• Menopause leads to estrogen deficiency, causing significant changes in vaginal physiology.
• Postmenopausal vaginal atrophy affects quality of life and necessitates therapeutic interventions.

Purpose of the Study:

• To investigate the physiological effects of estrogen replacement therapy on vaginal function in postmenopausal women.
• To compare post-treatment vaginal parameters with established norms for premenopausal women.

Main Methods:

• Hormonal and cytological assessments were performed.
• Vaginal pH, fluid quantity, transvaginal electropotential difference, and blood flow were measured.
• 14 women aged 51-70 years participated, with evaluations before and after therapy.

Main Results:

• Estrogen therapy led to a significant decrease in vaginal pH.
• A significant increase was observed in transvaginal potential difference, vaginal fluid quantity, and vaginal blood flow.
• Post-treatment results approached those of women under 40 years.

Conclusions:

• Estrogen replacement therapy effectively reverses key physiological changes associated with vaginal menopause.
• Treatment can restore vaginal function to levels comparable to younger women, improving gynecological health.
